Fundamental flaws break the series otherwise could have been a very good micro-management game.
If you could give unique orders to each and every train, bus and truck then you could effectively create a fully working city, and then A-Train 9 would even compete with the Sim City games! But since it seems you cannot, the game in general suffers greatly. Not to mention, the rigid building of roads and train tracks which could have done with more fine tuning options.
If the timetable issue wasn't a problem, A-Train 9 would have maybe deserved a 6/10 score - but the issue really is a fundamental problem and thus, really effects gameplay significantly.
